详细研究了大陆地壳的液体(以下从略)饱和条件以及地壳不同部分液体对地壳电导率和地震活动性的影响。在总结水文地质学、地球物理学和岩石学资料的基础上,取得了液体成分、状态和含液量等特性。指出了在地壳的中部和下部都存在着液体上移运动。变质过程是液体外移的主要缘由之一。变质过程促使孔隙层和裂隙层的形成,也促使无渗透性屏蔽层的形成。有关地壳现代饱和度的认识与地壳的电导、速度和吸收特性的资料相符甚佳。证明了这些特性与液体密切相关。根据一些新的地球物理学资料,又研究了壳内液流层的主要特性、液流层的分带性及其在主要地质构造中的差异。提出:脱水条件有异的一些板块之间接触面上所生压力是产生地震活动性的主要因素之一。
The effects of the saturation conditions of the continental crust liquid (hereinafter abbreviated) and the crustal conductivity and seismicity of the liquid in different parts of the crust are studied in detail. On the basis of summarizing the data of hydrogeology, geophysics and petrology, the characteristics of liquid composition, state and liquid content were obtained. It is pointed out that there is liquid upward movement in the middle and lower part of the crust. Metamorphosis is one of the main causes of liquid migration. Metamorphic processes promote the formation of pore layers and fracture layers, and also contribute to the formation of impermeable barriers. Knowledge of the modern crustal saturation is in good agreement with the crustal conductivity, velocity and absorption characteristics. It is proved that these characteristics are closely related to the liquid. Based on some new geophysical data, the main characteristics of the fluid-strata within the shell, the zonality of the fluid-flow layer and its differences in the main geological formations are also studied. It is proposed that the pressure generated at the contact surface between some plates with different dehydration conditions is one of the main factors that cause the seismic activity.
